Download or read book Understanding Innate Immune Signaling During Listeria Monocytogenes Vaccination and Its Implications for Cancer Immunotherapy written by Zachary Taylor Morrow and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Listeria monocytogenes is a gram-positive facultative intracellular pathogen that stimulates a robust CD8+ T-cell response and has been utilized for decades to understand various aspects of innate and adaptive immunity. Due to its ability to stimulate CD8+ T-cells, L. monocytogenes has been developed as a safe anti-tumor vaccine platform. Efforts to understand how L. monocytogenes primes CD8+ T-cell responses led to the observation that L. monocytogenes that fail to access the host cytosol do not prime robust CD8+ T-cell responses. This led us to hypothesize that activation of a cytosol-specific innate immune pathway was necessary for the optimal T-cell response toward L. monocytogenes. Counterintuitively, I show that two cytosol-specific innate immune pathways activated by L. monocytogenes, the production of type I interferon, and inflammasome activation are actively detrimental to, or are dispensable for the T-cell response, respectively. Type I interferon impairs the formation of memory precursor effector cells, leading to deficits in protective immunity, and is likely acting on antigen presenting cells. I aided in identifying that macrophages and dendritic cells produce PGE2 during L. monocytogenes infection. The production of PGE2 is the first cytosol-specific innate immune pathway identified that is necessary for the optimal T-cell response toward L. monocytogenes. I show that PGE2 production is dependent on the calcium-dependent cytosolic phospholipase A2 (cPLA2) and that calcium fluxes necessary for PGE2 production are likely emanating from inositol-triphosphate-signaling dependent endoplasmic reticulum receptors. Finally, in an altogether different approach, I show that L. monocytogenes can be engineered to express and secrete mammalian cytokines as an in-situ vaccine platform. Taken together, my work demonstrates how innate immune signaling informs adaptive T-cell responses during L. monocytogenes vaccination, and that L. monocytogenes can be engineered to modulate innate immune pathways resulting in a better vaccine platform. This thesis begins to unravel how the first cytosol-specific innate immune pathway necessary for T-cell priming is triggered and highlights new avenues for the therapeutic application of L. monocytogenes to combat cancer.
Download or read book Handbook of Listeria Monocytogenes written by Dongyou Liu and published by CRC Press. This book was released on 2008-04-21 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once feared as a deadly intracellular bacterium with the extraordinary capacity to survive a wide array of arduous external stressors, Listeria monocytogenes is increasingly recognized as a preferred vector for delivering anti-infective and anti-cancer vaccine molecules. A reliable, single-source reference on the fundamental aspects of this bacterium is crucial to support future study and further the advancement of biomedical sciences and intervention strategies. Drawn from an international panel of scientists with notable expertise in their respective fields, the Handbook of Listeria monocytogenes is divided into four sections: Section I discusses the biology and pathogenicity of this bacterium, including epidemiology and stress responses. Section II demonstrates identification and detection techniques such as phenotypic and genotypic identification, strain typing, and virulence determination. Section III details the current knowledge of genetic manipulation of Listeria, including comparative genomics, genomic divisions, epidemic clones and population structure, and analysis of cell envelope proteins. Section IV covers innate and adaptive immunity against Listeria, and examines the use of this bacterium for anti-infective and anti-cancer vaccine development. The first comprehensive compilation of knowledge in this area, this handbook is an indispensable reference for anyone embarking on the path of manipulation of Listeria as either a model for the study of the host-bacterium relationship or as a tool for delivering protective molecules to cytoplasm.

Download or read book Use of a Listeria Monocytogenes Protein to Stimulate Immune Responses and Anti tumor Effects written by Amber Leigh Ortiz and published by . This book was released on 2017 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural killer (NK) cells are a type of innate immune cell that secrete IFN when activated. IFN has pro-inflammatory effects and can act on tumor cells to kill them or inhibit their proliferation. NK cells can also exert direct anti-tumor cytolytic activity. Previous work showed that the Listeria monocytogenes (Lm) p60 protein indirectly promotes activation of NK cells to mediate cytokine production. The p60 protein contains two divergent LysM domains and one SH3 domain. The LysM1 domain is responsible for the immune stimulatory activity of the p60 protein and is present with the SH3 domain in a fragment of p60 termed "L1S." Like p60, recombinant L1S binds dendritic cells (DC) to stimulate their secretion of cytokines such as interleukin-18 (IL-18) and license them to promote activation of NK cells. The studies in this thesis investigated the nature of immune cell activation by L1S in vitro and in vivo through direct lung instillation. I found that instillation with wildtype L1S induced recruitment of inflammatory neutrophils and promoted accumulation of activated, IFN-producing, NK cells with increased cytolytic activity. I further showed that instillation of tumor-bearing mice with wildtype L1S protein significantly reduced burdens of established tumors. IFN and NK cells were required for these therapeutic effects. Further studies utilized simulated structure analysis and site-directed mutagenesis to explore the effects of specific amino acids in the LysM1 domain on the function of recombinant L1S protein. Specific amino acids in the LysM1 region were identified as critical for eliciting NK cell activity. Thus, my studies have improved our understanding of L1S immunostimulatory function and demonstrated its potential in vivo use for stimulation of NK cell anti-tumor responses.

Book excerpt: Examining the enormous potential of microbiome manipulation to improve health Associations between the composition of the intestinal microbiome and many human diseases, including inflammatory bowel disease, cardiovascular disease, metabolic disorders, and cancer, have been elegantly described in the past decade. Now, whole-genome sequencing, bioinformatics, and precision gene-editing techniques are being combined with centuries-old therapies, such as fecal microbiota transplantation, to translate current research into new diagnostics and therapeutics to treat complex diseases. Bugs as Drugs provides a much-needed overview of microbes in therapies and will serve as an excellent resource for scientists and clinicians as they carry out research and clinical studies on investigating the roles the microbiota plays in health and disease. In Bugs as Drugs, editors Robert A. Britton and Patrice D. Cani have assembled a fascinating collection of reviews that chart the history, current efforts, and future prospects of using microorganisms to fight disease and improve health. Sections cover traditional uses of probiotics, next-generation microbial therapeutics, controlling infectious diseases, and indirect strategies for manipulating the host microbiome. Topics presented include: How well-established probiotics support and improve host health by improving the composition of the intestinal microbiota of the host and by modulating the host immune response. The use of gene editing and recombinant DNA techniques to create tailored probiotics and to characterize next-generation beneficial microbes. For example, engineering that improves the anti-inflammatory profile of probiotics can reduce the number of colonic polyps formed, and lactobacilli can be transformed into targeted delivery systems carrying therapeutic proteins or bioengineered bacteriophage. The association of specific microbiota composition with colorectal cancer, liver diseases, osteoporosis, and inflammatory bowel disease. The gut microbiota has been proposed to serve as an organ involved in regulation of inflammation, immune function, and energy homeostasis. Fecal microbiota transplantation as a promising treatment for numerous diseases beyond C. difficile infection. Practical considerations for using fecal microbiota transplantation are provided, while it is acknowledged that more high-quality evidence is needed to ascertain the importance of strain specificity in positive treatment outcomes. Because systems biology approaches and synthetic engineering of microbes are now high-throughput and cost-effective, a much wider range of therapeutic possibilities can be explored and vetted.
Download or read book Immunization Safety Review written by Institute of Medicine and published by National Academies Press. This book was released on 2002-07-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: By two years of age, healthy infants in the United States can receive up to 20 vaccinations to protect against 11 diseases. Although most people know that vaccines effectively protect against serious infectious diseases, approximately one-quarter of parents in a recent survey believe that infants get more vaccines than are good for them, and that too many immunizations could overwhelm an infant's immune system. The Immunization Safety Review Committee reviewed the evidence regarding the hypothesis that multiple immunizations increase the risk for immune dysfunction. Specifically, the committee looked at evidence of potential biological mechanisms and at epidemiological evidence for or against causality related to risk for infections, the autoimmune disease type 1 diabetes, and allergic disorders.

Download or read book Actin based Motility written by Marie-France Carlier and published by Springer Science & Business Media. This book was released on 2010-09-23 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of actin by Straub in the 1950’s and the pioneering work of Oosawa on actin self-assembly in helical laments in the 1960’s, many books and conference proceedings have been published. As one of the most essential p- teins in life, essential for movement in organisms rangingfrom bacteria to higher eukaryotes, it is no surprise that actin has fascinated generations of scientists from many different elds. Actin can be considered as a “living treasure” of biology; the kinetics and thermodynamics of self-assembly, the dissipative nature of actin po- merization, the molecular interactions of monomeric and polymerized actin with regulators, the mechanical properties of actin gels, and more recently the force p- ducing motile and morphogenetic processes organized by the actin nanomachine in response to signaling, are all milestones in actin research. Discoveries that directly derive from and provide deeper insight into the fundamental properties of actin are constantly being made, making actin an ever appealing research molecule. At the same time, the explosion in new technologies and techniques in biological sciences has served to attract researchers from an expanding number of disciplines, to study actin. This book presents the latest developments of these new multiscale approaches of force and movement powered by self-assembly processes, with the hope to opening our perspectives on the many areas of actin-based motility research.
